Botanical name:
Shorea spp.
Growth area:
Malaysia and Indonesia; for the Dutch
market the main growth area: is Malaysia.
Quality:
Select and Better
Colour of heartwood:
Deep to light
red.
Colour of sapwood:
Grey / green +/- 50 mm wide rims.
Sapwood is not allowed for front wall panelling.
Mass density:
The timber industry requires Meranti of
at least 450 kg/m3. The weight of Meranti varies between 300 - 800 kg / m3.
Grain:
Generally rather straight-grained.
Fissure:
Internal fissure may occur during a forced
drying process. ‘Collapse' can be recognised by detecting the exterior warping
of the saw block.
Warping:
Meranti that was dried properly does not have
much tendency to warping; the mass density influences the extent of warping.
Heavy, deep red Meranti will warp more than light Meranti. For some
applications it is advisable to select on mass density first, for example for
components requiring large rebate cutting, for example side/bottom-hung sash
windows, flap windows and shutting stiles of lift sliding doors.

Knots:
Large, intergrown knots may occur. Whether or
not the part can be used must be assessed during production. Around the knots
extensive slope of grain occurs, which may cause warping.
Bio-substances:
Gums and resins. Generally, these are
not corrosive, but planing and cutting will cause large dust clouds. This is
why proper extraction is required.
Mould and insects:
Small wormholes may occur. A
limited extent of such so-called pin-holes is allowed for transparent finishes.
The pinholes do not affect the strength of the wood. Large wormholes may
sometimes occur. These must be cut out.
Durability grade:
3 - 4 - medium to low durability,
wall panelling work KVT'95 grade A
Gluing:
Good
Machining:
Can be machined with HS or hard-metal
tools. Very easy to saw, plane, profile, drill and sand. An ideal wood type for
traditional and sophisticated wood processing machines.
KVT:
KOMO certified: - solid - finger joints - finger
jointing / laminated Preserving: no
Paint systems: Solvent-based paint allowed;
water-based paint as a base system allowed. Finishing: - transparent - opaque. Hardness: hard
Dekker range:
Very extensive; see Elephant range
General applications:
Wall panelling, stairs, plinths,
frames and wall panelling etc. For special applications, the correct meranti
species must be selected.
